Question

3/6 + 3/12
4/12+2/4
3/2-10/12
11/12-2/3

Answer 1

3/6 + 3/12=18/36+6/36=24/36
4/12+2/4=4/12+6/12=10/12
3/2-10/12=18/12-10/12=8/12
11/12-2/3=11/12-8/12=3/12

Answer 2

$\frac{3}{6} + \frac{3}{12} = \frac{36+18}{72}= \frac{54}{72} simplificado = \frac{3}{4}$

$\frac{4}{12}+ \frac{2}{4} = \frac{16+24}{48}= \frac{40}{48}simplicado= \frac{5}{6}$

$\frac{3}{2}- \frac{10}{12} = \frac{36-20}{24}= \frac{16}{24}simplificado= \frac{2}{3}$

$\frac{11}{12}- \frac{2}{3} = \frac{33-24}{36}= \frac{9}{36}simplificado= \frac{1}{4}$
